Name of the Vulnerable Software and Affected Versions
PraisonAI versions prior to 4.5.97
Description
An authentication bypass exists in the multi-agent teams system where the
validate token() function within OAuthManager returns True for any token not found in its internal store, which is empty by default. Consequently, any HTTP request sent to the MCP server containing an arbitrary Bearer token is treated as authenticated. This allows an unauthenticated attacker with network access to the MCP HTTP server to gain full access to all registered tools and agent capabilities, including agent execution, workflow runs, container file read/write, and skill loading.Recommendations
Update PraisonAI to version 4.5.97.
